Chesapeake Bay Total Maximum Daily Load (TMDL) Tracking

Thursday, May 31, 2012

Martin Hurd , Vladislav Royzman, Tetra Tech, Inc.

Brian Burch, Megan Thynge, US EPA


Agenda

  • Background

  • BayTAS Overview

  • NEIEN Flow Implementation

  • Conclusions & Lessons Learned



  • Background - What is a TMDL?

  • Waste Load Allocations for point sources

  • Load Allocations for nonpoint sources

  • Reserve capacity sets aside allocation for future development

  • Margin of Safety allocation accounts for uncertainty


PA 2009 commitment for 2012 milestones


  • Background - BayTAS Progress

  • What is it?

    • Bay Tracking & Accounting System

    • Released January 28, 2011

  • Why Developed?

    • Required by Executive Order 13508, “Strategy for Protecting and Restoring the Chesapeake Bay Watershed” - May 12 2010

    • CBF Settlement Agreement “Begin” to use the system by Jan 31, 2011

  • What does it Track?

    • TMDL allocations and reserves

    • Tracks facility loads

    • Annual progress and milestones


  • BayTAS Overview - Tracking Progress

  • Tracks TMDLs for 92 Segments for:

    • State, Basin, Segment, Sector and Facility

    • Includes 5.3.0 and 5.3.2 model version data for delivered and edge of stream

  • Tracks WLAs for NPDES Point Sources and LAs for Non-Point Sources/Sectors

  • Stores TMDL Progress and model runs


  • BayTAS Overview - Tracking Progress

  • Data tracked for non-significant and significant facilities

  • Details include allocations, DMR data and whether meeting WLA


  • BayTAS Overview - Reporting Progress

  • GIS data viewer for viewing facility and allocation information

  • Web Services provide data to BayTAS public site on CSTAT

  • Excel / Word Management Report

  • Excel Data Extracts

  • Live Reports for NEIEN submissions


  • NEIEN ProgressBMP Exchange

  • Trading Partner Agreement (CBPO & Jurisdictions) signed in 2004 and $390K grant.

  • Goal to exchange BMP Implementation data by Dec 2010.

  • Best Management Practices (BMPs) are provided by jurisdictions and used as inputs to the suite of Bay Models

  • Results in nonpoint source loadings for given scenario

  • Submission reports are published in BayTAS


  • NEIEN Flow Implementation Progress

  • Created common exchange of BMP projects for agricultural, stormwater, and urban BMPs.

  • Leveraged the existing production BayTAS application

  • User management, admin functions, automated report publication for stakeholders.

  • Data from the exchange is consumed and processed for input into the Bay Model, using BayTAS/node functions, to determine load reductions and progress


  • NEIEN Flow Implementation Progress

  • Schema verification

  • Software & database development

  • Data content inventory

  • Data conversion & standardization

  • Reporting

  • Rules identify

  • Unit type (& unit conversions)

  • Priority of use

  • Target practice in SB / WSM

  • Conversion factors (mathematical operators & constants)

  • Stored procedure associated with record

  • Scenario Builder input file type

  • Status & Comments


  • NEIEN Flow Implementation Progress

  • State partners communicate requests to Admin & submit data

  • Admin updates system rules table & kicks off progress run

  • Data converted processed to Scenario Builder & validation reports for state partners


  • NEIEN Flow Implementation Progress

  • Live Reports – what is in the node database

  • Validation against SB Requirements:

  • Summarized numbers

  • Status – reason why

  • Link to details, individual records for the summary row

  • Diagnostic information for Admin - SP associated with conversion rules.



  • BayTAS Future Next Steps and Ongoing Efforts Progress

  • Implementation of planning targets

    • 2-year milestone load reductions

  • Programmatic milestones

  • BMP Implementation Verification Tracking

  • Trading and Offset Transactions

  • Permit Compliance Schedules

  • Schema Update and Maintenance


  • BayTAS Future Next Steps and Ongoing Efforts (Continued) Progress

  • Waste Water Data Enhancement

    • Data acquisition/loading from state partners

    • Data QA/QC functionality

    • Data handling calculations for missing values

    • Range checks

    • Parent & Component species summations

    • Chain of Custody reporting for confirmation

    • Consolidated source for CBPO applications
